ATOMIZER.

Specification of Letters Patent.

Patented Aug. 27, 1907.

Application filed December 10,1906. Serial No 347,152.

To all whom it may concern:

Be it known that I, THOMAS A. DE VILBIss, a citizen of the UnitedStates, and a resident of Toledo, in the county of Lucas and State ofOhio, have invented certain new and useful Improvements in Atomizers;and I do hereby declare the following to be a full, clear, andexact'description of the invention, such as will enable others skilledin the art to which it appertains tomake and use the same, referencebeing had to the accompanying drawings, and to the figures and lettersof refer- -ence marked thereon, which form a part of this specification.My invention relates to atomizers of the class particularly designed forthe reduction of liquids to the form of spray for inhalation or forapplication to the throat or nasal passages, and for other purposes.

The object of my invention is the provision in an apparatus of thisnature of a valve adapted to be moved to either open or close the liquidand air channels thereof whereby the bulb or actuating agent may beoperated or the apparatus turned in any position without the escape offluid either in liquid orspray form therefrom, thus adapting theapparatus for use by travelers or the like, as it can be packed withoutremoving the liquid therefrom and without liability of its leaking andsoiling other articles packed therewith.

The operation, arrangement and construction of the parts of theinvention are fully described in the following specification, andillustrated in the accompanying drawings, in which,

Figure 1 is,a perspective view of an atomizer of the vacuum typeembodying my invention. Fig. 2 is an enlarged central horizontalsectionlof the vessel cap and associated valve, with the latter in openposition. Figs 3 and 4 are similar views with the valve plu'g removed inthe former and in closed position in the latter. Fig. 5 is a centralvertical section of the cap and valve plug, with the latter in openpositipn. Fig. 6 is a bottom view of the cap and valve plug assembled.-'Fig. .7 is a vertical section on the dotted lines a: a: in Figs. 2 and5. Figs. 8 and 9 are similar sections, respectively, on the dotted linesy y and z y in Fig. 5, the former showing the cap secured to the neck ofa liquid receptacle. Fig. 10 is a view of the side oithe valve, plugdisposed toward the nozzle when the plug is in open position.

Referring to Figs. 1 to 10 of the drawings, 1 designates the liquidreceptacle of an atomizer; 2 a plug or cap for closing the neck thereofand which is shown as being threaded to a. collar 3 secured to thereceptacle neck; 4 the nipple to which the, tube of the air-supplythelower end of which latter is intended to be submerged in the liquidcontained in the receptacle.

In carrying out the idea of my invention I provide the cap-head with atransverse tapered cylindrical opening 12 at substantial right'angles toand intercepting the channels 8 anil 10 therein, as shown, and mounttherein a tapered valve-plug 13. This plug is prevented from removalfrom its casing. in any suitable manner, as by threading a nut 14 to itsreduced end, and to facilitate its turning has its other end formed witha suitable finger grip, as 'shown. Provided through the plug 13 are thestraight channel 15 and angled channel 16, the former registering at itsends with the separated portions of the channel 8 in the caphead, asshown in 2 and 7, and the latter registering at its ends with theseparated portions of the channel 10 in the cap-head, as shown in Figs.2 and 9, when the plug is in what maybe termed open position relative tothe cap, thus opening communication between the air-supply means andnozzle 6 in the one instance and the interior of the receptacle 1 andnozzle 6 in the other instance. Extending laterally from the channel 15of the plug is a needle-point aperture or duct 17, which, when the plugis in open position, is intended to communicate with the interior of thereceptacle through the small channel or duct 18 in the cap-head, asshown in Figs. 5 and 7. The channel or duct 17 in the plug has its outerend enlarged, as shown at 19, to insure its registering with the channelor duct 18 when the plug is turned to open position. The purpose ofthe'channel 1718 is to permit a small portion of the air passing throughthe channel 8-15 in the cap-head and plug to enter the receptacle abovethe liquid therein, thus creating a pressure on its surface andeffecting a heavier ejection of spray from the nozzle 6 than would beoccasioned by the air suction alone. As the provision of thiscommunication between the air-supply and the interior of the vessel hasa tendency to fiood the tube 9 and eject the liquid in stream ratherthan spray form it is only intended for use in emergencies, such, forinstance, as cleaning the liquid tubes should they become clogged, andthe pressure thus created in the vessel is normally released therefromthrough the vent channel 20. This channel is provided through thecap-head and plug, as shown in Fig. 8, and opens communication betweenthe interior of the vessel and the atmosphere.

By closing the outer end of the channel 20 with the thumb or finger theair pressure within the vessel exerts itself upon the liquid and causesthe ejection thereof fromthe nozzle 6.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is,

1. In association with the receptacle and the air and liquid passages ofan atomizer, a valve member,'which, whenjn open position, has a channelin register with the air-passage, a channel in register with the liquidpassage,

and a channel opening communication between the interior of thereceptacle and the atmosphere.

2. In association with the receptacle and the air and liquid passages ofan atomizer, a valve member which, when in open position, has a channelin register with the air-passage, a channel in register with the liquidpassage, 11 hy-pass from the air-channel into the receptacle, and achannel opening communication between the interior of the receptacle andthe atmosphere.

3. In combination in an atomizer, a receptacle, a cap for closing themouth of the receptacle and having air and liquid passages therethroughand a transverse opening intercepting said passages, and a valve-membermounted in said opening and when in open position having channels inregister with the air and liquid passages, a restricted bypass from theair-channel into the receptacle, and a vent channel openingcommunication between the interior of THOMAS A. DE VILBISS.
